Folks,
Ok, I now believe it is the Mackie Control Surface. I simply couldn’t find an “absolute” way to prove this, and still can’t, but the circumstantial evidence points to the surface. Case in point, it will not operate properly using the port 2 midi I/O. Interestingly data flows to the surface (moving faders and operating the counter) but “NO” data flows up the midi connection—verified by the midi light on the Midex8–and yes, I tested the same connection with an old Motormix–it was fine. Tried another DAW among other things…same thing. Case closed. I got a bad Mackie MCU Pro out of the box.
Best, Ted
